SPECIFICATION forming part of Letters Patent No. 765,908, dated July 26, 1904.

Application filed November 28, 1902.- erial No. 133,017. (No model.)

To all whom, it may concern.-

Be it known that I, ALBERT J. THORNLEY, a citizen of the United States, residing at Pawtucket, in the county of Providence and State of Rhode Island, have invented a new and useful Improvement in Spool-Machines, of which the following is a specification.

This invention has reference to woodworking-machines, and more particularly to that class of machines known as spool-machines for automatically making spool-blanks from wood.

The object of this invention is to facilitate the operation of making spool-blanks, to make a more perfect blank at a greater speed and at less cost than has heretofore been done.

The invention consists in the peculiar and novel construction of the machine and its parts whereby the stock is automatically fed in the machine and is turned, drilled, and cut off in successive and continuous operations, as will be more fully set forth hereinafter.

Figure 1 is a front view of my improved spool making machine, showing the main driving-pulley, the gearing from the main shaft to the feed-rolls, the reverse-gearing for running the stock back when required, and the cam for operating the drill. Fig. 2 is a view looking at the left-hand end of the machine, showing the lever for operating the reverse-gearing, the feed-rolls, and the cam with its connecting-lever with the rock-shaft to move the circular saw forward and backward when required. Fig. 3 is a View of the righthand end of the machine, showing the main shaft and pulley, the drill-arbor and its pulley, and the stop-arm for limiting the forward movement of the work with the belts going to the different pulleys in broken lines. Fig. A is a plan view showing the gearing from the main shaft to the feed-rolls, the cutter for turning the stock, the movable stop-arm for limiting the forward movement of the stock, the drill for boring, and the saw-arbor with its pulley and saw for cutting off the finished blank. Fig. 5 is a rear view of the rockshaft supporting the saw-arbor frames, showing the cam-lever secured on the right-hand end and the stop-arm on the left-hand end, the bearings being broken away from the frame of the machine. Fig. 6 is an enlarged face View of the cutter, which revolves in the direction shown by the arrow. Fig. 7 is an enlarged sectional View taken lengthwise through the shaft-pulley and cutter, showing the stock as it enters the cutter-square in the direction of the arrow and after it has been turned around by the cutter. Fig. 8 is an enlarged detail sectional View showing a part of the frame and bed supporting the rock-shaft bearing, the circular saw for cutting off the blank, the support for the blank, and the tension-guide device for frictionally holding the work in its proper position. Fig. 9 is a View showing the slip-gearing on the main and front shafts to give an intermittent motion to the feed-rolls. Fig. 10 is an isometric perspective view of the completed spool-blank.

In the drawings, a is the frame of the machine, with the base a, the bed (0 and the extension a having the bearing a for the righthand end of the main shaft 6. This shaft 6, carrying the main pulley 6, extends through the frame a in suitable bearings and carries the slip-gear b meshing with the slip-pinion b on the front shaft 6*. The slip-gear has thirty teeth with a blank space equal to fifteen teeth, and the slip-pinion 6 has thirty teeth with ablank space equal to five teeth, as shown in Fig. 9. By this slip-gearing an intermittent motion is given from the main shaft to the front shaft 6*, supported in the bearings a and a. on the frame a, and the bevel-gear b meshing with the bevel-gear Z) on the reverse gearing shaft F. This shaft extends upward from the base a in the bearings a, a and the bracket a", secured to the bed a.

Splined to the shaft 6 is the sliding clutch Z2 operated by the fork b on the rod'b This rod slides in the bearings a and (0 and is controlled by the reversing-lever 6 through the pin 6 on the rod Z) working in the slot 7) in the reversing-lever to raise and lower the clutch 6 as shown in Figs. 1 and 2.

port a for holding the stock while the circular saw is in operation, as shown in Fig. 8.

On the upper part of the frame extension (4" and on a line with the center of the cutter (Z are the bearings (o a for the drill-arborf, carrying the drill f, the pulley f for revolving the drill, and the grooved collar as shown in Figs. 1 and 4:.

Pivotally secured to a lug on the frame we tension (4 is the lever f, with the fork f on its upper end having the pins f", which enter the groove f in the collar f, and on its lower end the roll f which enters the groove f in the cam f on the main shaft 6. As this cam revolves it gives a reciprocating motion to the drill-arbor f and the drill f by the lever f".

Secured to the bed a at the rear of the machine are the bearings a a for the rockshaft g. Fastened to this shaft is the stoparm g with the stop 9 The saw-arbor g, with the circular saw g" and the pulley g, is mounted in the frame g secured to the rockshaft g. On the end of the rock-shaft opposite the stop-arm g is secured the lever g with the roll g engaging with the groove g in the cam g on the main shaft Z). The rotation of the cam g gives a reciprocating motion to the saw-arbor, bringing the saw forward and backward at a predetermined time to cut off the spool-blank from the stock.

The several figures in the drawings are all shown in the position the machine would assume when starting to make a spool-blank.

In the operation of the machine power is the lever secured on the end of the rockshaft. The stop on the stop-arm g, secured to the rock-shaft g, moves forward with the saw and out of the way of theblank when the saw has completed its out, allowing the finished blank to drop out. It then moves back into its former position, forming a stop for the next blank.

If thought desirable, a chute may be placed to receive the completed blank and carry it to a receptacle on the floor or base of the machine.

Having thus described my invention, 1 claim as newand desire to secure by Letters Patent- 1. In a woodworking-machine for making spoolblanks, a power-shaft, a stop secured to an arm on a rock-shaft, a circular saw supported on and moving with the rock-shaft, a cam on the power-shaft, and a lever connecting the cam with the rock-shaft to partly rotate the rock-shaft and move the stop with the saw forward and out of the way of the blank when the saw has completed its out.
